IMPROVEMENT IN PAPER-BAG MACHINES.

Specification forming part of LettersPatent No. 188,3'28,dated March 13, 1877; application filed v September 22, 1876.

To all whom it may concern:

Be it known that l, SYLVESTER L. KING, of the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machinery for Forming .and Pasting Satchel-Bottoms of Paper Bags; and Ido hereby declare that the following is afull, clear, and exact description of the same, reference being had to the ac- V c'ompanying drawing, which forms part of this specification.

This invention relates to machines for-forming and pasting or securing what are known as satchel-bottoms on paper bags from fiat paper tubes after the latter (of orfrom whichboth the bottoms and bodies of the bags are .machine' constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section of the same, mainly on the line a; 00. Fig. 3 is a plan thereof, and Fig. 4 an end view of the same. Fig. 5 is an underview of a satchel-bottom from the exterior of a paper tube as produced by the machine. Figs. 6, 7,8, and 9 are sectional views of the opening, folding, and pasting devices in different working positions; and Figs. 6, 7, 8*, and 9' are perspective views of a paper'bag in, part, with its satchel-bottom as in the act of being formed when the opening, folding, and pasting devices are in the positions represented for them by Figs. 6, 7, 8, and 9,respectively.

The machine consists, generally, in a com bination of opening and closing flaps within which the paper tube is received and held, hooks for spreading the ends "of the tubes, and formers or folders and pasters for making the satchel-bottoms on the one end of each tube, the whole rotating on or around a central axis.

A A- are opposite end frames, between which the machine rotates on or by a shaft, B, motion being communicated to the latter by means of gearing or otherwise. This shaft B forms the central axis, on opposite sides of which the paper-tube-folding and satchel-bottom-form ing devices are duplicated or arranged. Thus the machine, for one-half or thereabout of its length, is composed of aframe made up of hinged and fixed wings or flaps 0 (you opposite sides of the shaft or axis B, and tablesections D D, fast on the inner ends'of said flaps, and projecting at right angles from the outer faces of the latter. 0 0 are the hinged or opening and closing flaps, with their attached table-sections D D; and U 0 are the fixed flaps with their attached table sections D D.

The opening and closing flaps O .O,-with their attached table-sections D D, arere-.

versely hung by means of their hinges c 0, so that when by the rotation of the machine the fixed flaps G O are in a horizontal position one of the hingedflaps Gis open by'action of its Weight in relation with its fixed flap 0, while the other hinged flap C is closed by action of 7 its weight in relation with its corresponding fixed flap O. This provides-for the introduction of the longitudinally-seamed paper tubes E between each pair successively of hinged and fixed flaps G U, and in due course for the delivery of the same after the satchel-bottoms have been formed and pasted or secured on one end of said tubes.

The machine for the other half or portion of its length is made up of the devices which spread theend of the tube corresponding with the bottom of the bag, and which form or fold and paste said bottom. These devices are duplicated for each pair of hinged and fixed flaps G G,'and operate alternately in reverse relation with each other, so that the description of one set of said devices applies equally to the other set thereof. Thus, in explanation of either one set of such devices, the paper tube E is introduced between either one pair of hinged and fixed flaps O 0 when the hinged flap O is open, and said tube placed or adjusted so that its end to be closed is made to receive within it hooks F F, as shown in Figs. 6 and 6. These hooks project from axles b b, arranged in parallel transverse relation with the table-sections D D, and drawn toward each other by a spring, 8, to place the hooks F F in entering position within the paper tube. The axles b I) carry on their ends wheels (I d, which are arranged to travel on or along inclines e e on opposite sides of the table sections D D, and which are connected,'by rods ff, with a frame, G, fitted to slide on or along the shaft B by means of fixed cams, one of which, 9, only is shown.

As said frame G, during the rotation of the machine, is forced inward along the shaft- 13,

the wheels d 11 travel outwardly along the inclines e e, and draw the hooks F F away from each other, as shown in Fig.7, and cause said hooks to spread or open the end of the paper tube E from points 71, 11. on its opposite sides, and ultimately to cause said sides to overlap one another transversely, as shown at i, Fig. 7. This gives a flattened-out four-cornered closed construction to the end of the paper tube E, projecting beyond the table-sections D D of the closed flaps G O, which hold the body of the tube within them, the hooks F F releasing hold on the points h h as the closed end of'the tube E is laid on or over rocking formers or folders H H, near the adjacent edges of the table-sections D D, and a paste-- reservoir, I, approaches the intermediate portion of the-closed end of the tube. This pastereservoir I, which may be supplied and kept filled from opposite sides by receivers is 70, fornis a part of the frame G, or is carried thereby.

The-rocking transverse formers and holders H H are of an angular construction intermediately of their length, corresponding with the triangular construction of the sides ll, Fig.

8 of the closed tube end, and made male and female at their points, so that when the frame G, as in Fig. 8, is worked inward it'bears upon toes m m, to turn the formers or folders H H, causing the latter to bend or turn up the pointed portions h h of the paper tube against the sides of the paste-reservoir I, (see Figs. 8 and 8%) or rather opposite angular pastingoutlets n, corresponding with the acting portious of the formers or folders H H. As this action takes place, plungers 0, coming down or against the closed partially-folded end of the paper tube, act upon slides o, to deliver the paste against the inner faces of the pointed portions h h of the partially-folded end of the tube, said slides being returned or closed by means of springs to w. tion the toes m m, which are formed with books or noses r r, are caught by, or madeto enter, slots in elastic arms y y, attached to the sliding frame G, so that when said frame recedes from the table-sections D D it acts first upon one, and then upon the other, of the hooked portions of thetoes m m, tocause the formers or folders H H to turn over the pasted inner. faces of the pointed or angular portions h h of the closed end of the tube upon said closed end and each other, as represented in Figs. 9 and 9 of the drawing.

Thefurther or continued retrocession of the frame G from the table-sections D D causes springs K to return the formers or folders H H to their normal positions, as the hooks F F again approach each other to, in due course, repeat their operation. The machine continuing to revolve, allows the bag thus formed with a satchel-bottom to fall out from between the hinged and fixed flaps O 0, when the hinged flap comes undermost and opens by its weight. The like action takes place alternately or successively 'on opposite sides of the machine.

I claim- 4 1. The combination, with the hinged flaps O O and fixed flaps D D on reverse sides of'. the central shaft B, with which they revolve,

of the hooks F F, arranged to Work inward and outward in oblique directions'relatively to said shaft, essentially as and for the purpose herein set forth.

-2. The combination of the table-sections D D, having inclined planes or surfaces e e, the sliding frame G, the rodsf, the axles or shafts b, the wheels (1, and the hooks F, substantially as specified.

3. The rocking folders and formers HH,

provided with toes m in, in combinationwith the sliding frame G, the elastic slotted arms 3/ y, and'the paster or paste-tank I, essentially as described.

Signed this 6th day of September.
